Doomsday Bunker Upgrade

Three months passed quickly.

The excavation work is going very smoothly. More than 90% of a tunnel deep into the ground has been completed, and there is only a short distance left to open up the underground lair of alien creatures.

And the military is also making intensive preparations. The latest laser assault vehicle has been equipped with the team that is about to launch the attack as the vanguard, and it has figured out a set of usage methods in the past three months. relevant tactics were formulated.

Although this kind of laser assault vehicle is only equivalent to a heavy machine gun in terms of power, after it was actually put into use, the military concluded that laser weapons are much easier to use than heavy machine guns.

Compared with the crane machine gun, which needs to carry a large amount of ammunition, and may cause ricochet and accidental injuries during use, laser weapons completely avoid these shortcomings, and can provide continuous and stable fire support for troops, effectively suppress alien creatures, and greatly improve the combat effectiveness of troops.

After all, if a heavy machine gun is used in an underground tunnel for an hour, it can fire tens of thousands of bullets. Even if accidental injuries caused by ricochets are not taken into account, tens of thousands of bullets still need a truck to tow them.

Now with laser weapons, the consumption of this part of ammunition can be completely eliminated.

Satisfied with the laser weapon, the military even tried to install it on the spider robot that Chen Xin provided to the military.

Compared with the assault vehicle, the spider robot is obviously more suitable for the tunnel environment. Originally, Chen Xin also provided the military with a model equipped with a heavy machine gun, and the military was very satisfied with the use.

However, compared to the current version equipped with laser weapons, the original heavy machine gun version is naturally not so attractive.

If it weren't for the fact that the production of spider robots is more complicated and time-consuming than that of assault vehicles, the transformation of existing fire support spider robots is also more troublesome. The laser weapon module must first be supplied to the production of assault vehicles, and the military may want a large number of them. A spider robot equipped with a laser weapon.

But three months is really too short. Even with the factory's desperate production, the total number of laser weapons delivered to the troops is less than 200.

About one hundred of them were installed on the assault vehicle, more than fifty were installed on the spider robot, and the remaining dozens were used as spares for replacement.

Among the dozens of spare laser weapons, more than a dozen were tentatively installed on the official Titan by some thoughtful technicians. After some tests, they also had good results.

With these laser weapons, it is naturally impossible for the military to just wait like this and select the best combat troops among them. The military sends them into the underground tunnel that has been temporarily converted to defense to test these new weapons. Effects of using weapons.

It has to be said that the laser weapon has a satisfactory effect. In the military test, the troops equipped with the laser weapon completed the operation at a much higher speed than the original attack, and cleared a tunnel very cleanly.

If it wasn't for the fact that the military didn't have a plan to continue the attack and let them withdraw directly after the suppression, it would be impossible to say that this tunnel was attacked just like that.

This is undoubtedly much more efficient than the military's laborious and repeated saw-saw with alien creatures.

This undoubtedly greatly boosted the morale of the military, and also gave them more confidence in the counterattack plan. If they can continue to clean up underground creatures with such efficiency, the military even feels that they don't need to rely on the excavation plan, and they are also sure. Clear the alien creatures underground in the Dongting Lake area within a month.

Of course, the premise is that the aliens have no other moths.

But things are often expected. According to Murphy's theorem, if a bad thing is about to happen, it will happen. With only a short distance left in the excavation operation, the construction team expanded the tunnel according to the original plan. In order to build the advanced base, accidents still happened.

—————————————

During the excavation process of the tunnel, detectors have been monitoring the formation around the tunnel to prevent the possibility of piercing through an underground tunnel or cave during the excavation process.

At the same time, it is also monitoring the activities of alien creatures in the surrounding tunnels and caves, so as to avoid being dug by them and interfering with the construction.

The previous excavation work has been going smoothly. Relying on a line determined by geological surveys that completely avoids existing underground tunnels and caves, during the tunnel excavation construction process, there was no interference from alien creatures.

But when the excavation of the tunnel was less than 100 meters away, and the construction team had already started to expand the tunnel into a forward base, the surrounding alien creatures seemed to be crazy, and all of a sudden they all moved towards the excavation position of the tunnel. Drilling a hole, with the momentum of vowing to dig through it.

This undoubtedly triggered the alarm. The construction team adopted an emergency plan and hurriedly evacuated all the workers. At the same time, in order to protect the precious shield machine, it was also disassembled in the shortest possible time, and evacuated from the ground together with the evacuated workers. come out

It took three months to dig down, but it took less than half a day to get out.

After the construction team withdrew, the army conveniently and quickly entered the tunnel, and made preparations for combat based on the detected alien biological activities.

When the first worker ant body dug through the wall of the tunnel and came out of it, a laser beam invisible to the naked eye instantly irradiated its head, and then it exploded into a knocked-out ant in less than a second. Rotten watermelon.

Immediately, more alien creatures poured into the tunnel and began to attack upwards.

However, human beings have already made preparations. With the help of the fire control system, dozens of laser weapons continuously fired at these alien creatures. The offensive has been affected.

But these alien creatures did not stop, but continued to dig the tunnel completely at the risk of huge casualties, allowing more combat daughters and worker ant daughters to pour into the tunnel.

Because the tunnel is almost a straight line, human beings naturally do not have the limitation of being unable to take advantage of weapons when fighting in underground tunnels due to the curved terrain. While the newly equipped laser weapons are showing great power, heavy machine guns and The light machine guns are not far behind, and while scatter a lot of ammunition, they send death to the alien creatures.

However, out of fear of blowing up the tunnel, the military still did not use large-caliber artillery and powerful explosives.

In this way, the Yan Kingdom military's counterattack against the underground alien creature's lair in the Dongting Lake area began when the human side did not expect it, but was prepared.
